Review comment: Maybe we should not guide the users to set the `default` service account here since any service account with enough permission will work. Also in the production environment, I think no one will use the `default` service account. Another thing is that we need to note here that users should set the [ServiceAccount](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/) for JobManager deployment/job and TaskManager deployment manually in the yaml files. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
